Forekomst og Udbredning. Vi liar under vor Ex- 
pedition noteret denne smukke og anselige Oopepode fra 
ikke mindre end 12'forskjellige Stationer. Paa de aller- 
fleste af disse blov Exemplarerne optagne med Trawl eller 
Bundskrabe fra megct betydelige Dybder, medens Overflade- 
nettet her, selv om det samkedes dvbt under Vandskorpen 
ikke bragte et eneste Exemplar op. Det er heraf sikkert, 
at Arten paa disse Punkter lioldt sig i de dybere Vandlag. 
Noiagtig at angive, fra hvilken Dybde de er optagne, lader 
sig dog vanskoligt gjore; men der er Grand til at antage, 
at de stammer fra de under det tempererede Atlanterhavs- 
vand liggende iskolde, Polarhavet oprindelig tilhorende 
Vandlag. 
Arten, der, som ovenfor anfort, forst er beskrevet som 
.sserskilt Art af A. Boeck, og senere af Moebius fra Pom- 
meranias Expedition i Nordsoen. forekommer ikke ualmin- 
delig langs vor liele Kyst, men opnaar her paa langt nmr 
ikke den Udvikling som i Nordhavets store Dyb, hvorfor 
man er berettiget til at anse den for en hoinordisk Form 
i Modsaetning til E. Prestandrece. der er en sydlig eller 
Atlanterhavsform. 
of the left leg, and lias a.t the point extending inward a 
very small, somewhat unguiform appendix, representing the 
rudimentary inner branch. The next articulation is slightly 
inspissated in the middle, and very movable connected 
with the preceding. The 3rd articulation is consider- 
ably shorter, and bears at the point several exceedingly 
complicated appendices, some of which are furnished with 
bristles, others with cilia, others again with short spines 
(see fig. 21). This pair of legs deviate very much, as to 
structure, from the male of Euchceta Prestandrece, the ter- 
minal claw on the left leg being in this species considerably 
longer, and acutely pointed; the appendices, too, at the ex- 
tremity of the right leg present quite a different appearance. 
All the specimens brought up on the Expedition from 
a great depth were distinguished by a vivid blood-red 
hue, also characterizing most of the appendages of the 
body, save the caudal bristles, which were quite pellucid, 
and whose dense cilia kept constantly shifting in all the 
tints of the rainbow. On the other hand, a few smaller 
examples, taken off the Storeggen Bank, near the surface 
of the water, in the finemcshed tow-net, had a far less 
conspicuous coloration, being • as usual quite translucent, 
with only the faintest reddish tinge over certain parts of 
the body. The eggs in the ovisac are, as stated above, 
of a beautiful blue colour. 
The length of the largest specimens obtained on the 
Expedition reaches 12 mm , — a colossal size for a free Co- 
pepod. The form generally met with off the Norwegian 
coast attains 1 but little more than half that length. 
Occurrence and Distribution. — On the Norwegian 
Expedition we had to record this beautiful and large-sized 
Copepod from as many as 12 different Stations. At by 
far the greater number of these, the specimens were brought 
up in the trawl or dredge, from very considerable depths, 
whereas the surface-net, even when sunk in these localities 
to a depth comparatively great, never succeeded in taking 
a single example. Hence, it is obvious, that the 'species 
hereabouts must inhabit the deeper strata. Meanwhile, to 
give the precise depth from which the specimens were col- 
lected, would be a difficult matter; but there is reason to 
assume as the habitat of the species the ice-cold strata of 
the Polar current, extending beneath the temperate Atlantic 
water. 
This form, which, as stated above, was first described 
specifically by A. Boeck, and subsequently by Moebius, 
from the “Pommerania” Expedition in the North Sea, occurs 
not infrequently along the entire range of the Norwegian 
coast, though far from attaining there a development com- 
parable to that it exhibits in the great deeps of the North- 
ern Ocean; and hence we are warranted in regarding the 
animal as a high Northern form, in contradistinction 1° 
E. Prestandrece, which is a southern or Atlantic species.
